我无法执行 npx react-native run-android，Java 错误； 无法确定任务“:app:compileDebugJavaWithJavac”的依赖关系。 LINUX

Question

有很多 Mapping new... 日志，所以我删除了一大块，因为我超出了可用字符数

（我不确定这是否是问题所在）它说这与许可证有关，但据我所知，我已经全部接受了。

在图片中，我向您展示了我通过 Android Studio 安装的内容，一切似乎都很好。

Answer 1

它基本上表明它缺少build-tools;30.0.2 Android SDK Build-Tools 30.0.2 platforms;android-30 Android SDK Platform 30

通过 Android-Studio 安装它们，一切正常。

除此之外，我还有另一个问题（可能与上面的问题无关，但我仍会在此处添加）

所以，现在，如果我再次尝试npx react-native run-android ，则会弹出以下错误

[adb]: Cannot run program "/home/u/platform-tools/adb": error=2, No such file or directory

platform-tools位于~/Android/Sdk中，而不是~/中。

基本上这意味着路径是错误的。 修复是在这里
